摘要：

The radiation motion of ships advancing in waves is the primary cause of added wave resistance. In this paper, 3D expression of radiation energy of ship hull with forward speed is derived. 3D translating and pulsating source is used to obtain velocity potential of flow field and then added resistance due to radiation motion of ship is calculated by the radiation energy principle based on 3D hydrodynamic coefficients and ship motions. Some results from existing methods based on strip method are shown for comparison. Added wave resistances of Wigley III hull, S175 containership and a tanker with various forward speed are carried out and analyzed in frequency domain. The numerical results are validated for the models by comparing them with experimental data. The present method provides a rapid and efficient approach to predict added resistance of ships in waves. © 2018, Editorial Board of Journal of Ship Mechanics. All right reserved.
